VIII. Common Mistakes in Product Selection
| Misconception | Correct Understanding |
|---|---|
| The thicker the galvanized coil, the better | Coating weight is more important than thickness; select appropriate zinc coating based on environment |
| All pre-painted coils have the same color performance | PVDF coating has far superior color retention than PE; PVDF is recommended for coastal areas |
| Stainless steel never rusts | Corrosion can still occur in strong acid or high chloride environments; proper material selection is essential |
| Aluminum coil has low strength | Aluminum alloys (e.g., 5052, 6061) can achieve structural-grade strength |
| Aluzinc is expensive and not cost-effective | Lower life-cycle cost; service life is 2-3 times that of galvanized steel |
